MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER As shown in the figure below, two masses m = 4.40 kg and m2 which has a mass 60.0% that of m, are attached to a cord of negligible mass which passes over a frictionless pulley also of negligible mass. If m and m2 start from rest, after they have each traveled a distance h = 2.90 m, use energy content to determine the following. m m (a) speed v of the masses 7.53 m/s (b) magnitude of the tension T in the cord 31.311 What forces contribute to the net work done on m? Are these forces conservative or nonconservative force? What forces acting on m are responsible for any changes in the mechanical energy of m? How is the change in mechanical energy of m1 related to the work done by the tension in the cord and to the change in kinetic and potential energy? Based on the definition of work done by a force, how is the work done by the tension in the cord related to the tension?

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A box slides from rest down a frictionless ramp inclined at 39.0 with respect to the horizontal and is stopped at the bottom of the ramp by a spring with a spring constant of k = 1.50 104 N/m. If the box has a mass of 12.0 kg and slides 3.00 m from the point of release to the point where it comes to rest against the spring, determine the compression of the spring when the box comes to rest. 0.17 m point of release
